DIY induction heating boiler. How to make an induction boiler with your own hands. Getting Started

Do you want to furnish your home with efficient and at the same time cost-effective heating? Then be sure to pay attention to modern induction boilers. Such units are characterized by high productivity and at the same time have an extremely simple design, so you can easily handle the assembly of an induction heating boiler with your own hands. The operation of the equipment in question is based on the use of inductive electrical energy.

Such boilers are absolutely safe and environmentally friendly. During their operation, no by-products are released that can harm humans and the environment.

By design, such boilers are a kind of electric inductors, which include two short-circuited windings.

Thus, the internal winding is responsible for converting incoming electrical energy into special eddy currents. An electric field is formed in the unit, which subsequently enters the secondary coil. The latter simultaneously performs the functions of the heating element of the heating unit and the boiler body.

The secondary winding is responsible for transferring the generated energy directly to the coolant of the heating system. Special oils, antifreeze liquids or clean water are used as coolant in such installations.

The internal winding of the heater is exposed to electricity. As a result, some voltage appears and eddy currents are formed. The created energy is transferred to the secondary winding, after which the core begins to heat up. Once the entire surface has been heated, the coolant will begin to provide heat to the radiators, and they to the heated rooms.

Is it rational to assemble the boiler yourself?

Induction heating boilers have a simple design; there are no difficulties with their assembly. However, you will definitely have to at least carefully study the proposed instructions and make efforts to correctly assemble a high-quality unit.

The reward for your efforts will be efficient and financially beneficial heating equipment. To assemble the boiler, you do not need to buy any expensive components - all the necessary elements are sold in ordinary construction, hardware and other specialized stores.

Provided that the finished unit is properly assembled and handled properly, it will easily last 20 years or even more. The main thing is to do everything in strict accordance with the instructions.

You are not given any extremely complex tasks, and it is almost impossible to make any critical mistakes when assembling an induction boiler according to the instructions.

Assembling a simple induction boiler

To assemble an induction boiler, you do not need to use any difficult-to-use tools or expensive materials. All you need is to have at least a basic understanding of the operation of an inverter-type welding machine.

First step. Cut the stainless steel wire or rod into pieces about 5 cm long. The required diameter of the wire used is 7-8 mm.

Second step. Prepare a plastic pipe to assemble the device body. A product with a diameter of about 50 mm will be sufficient.

Third step. Cover the bottom of the main pipe with fine mesh wire mesh. Select a mesh with such cells that pieces of loaded stainless steel or wire rod cannot pass through them.

Fourth step. Completely fill the housing with wire or rod, and then cover the free hole in the tube with a second metal mesh.

Fifth step. Carefully and as tightly as possible, wind about 90 turns of copper wire around the middle part of the body.

Sixth step. Connect special adapters to the heater body for insertion into the heating or plumbing system. The scheme is extremely simple: water enters the heater through one adapter - it heats up almost instantly - it exits into the heating system through the second adapter - the batteries and pipes give off heat to the room being served.

As a result of such simple manipulations, you will receive an inexpensive and extremely easy-to-assemble device for effective heating. The advantage of using a homemade induction boiler is that there is no need to allocate a separate boiler room for its installation. You simply cut out a piece of pipe near the entrance to the radiator and attach your homemade heater in its place.

Important: do not turn on the heater if there is no coolant in the heating system. In such a situation, the plastic body of the heater will simply melt and all your work will go down the drain.

Be sure to reliably ground your homemade heating device.

Design of a vortex induction heating unit

Assembling such a unit will require you to have certain skills in handling a welding machine, as well as a three-phase transformer. The advantage of a vortex heater is that it does not contain elements that cannot withstand intense loads for a long time. That is, the risk of early boiler failure is reduced by an order of magnitude.

Also among the advantages of the unit in question is the absence of detachable connections. This allows you to completely forget about the risk of leaks.

A homemade vortex induction boiler operates in almost silent mode. This allows you to mount it in any desired location. There are also no harmful exhausts, so you don’t have to worry about the need to arrange a reliable boiler room and install a chimney.

First step. Weld a pair of metal pipes with a diameter of about 2.5 cm together so that the result is a round-shaped product. The resulting workpiece is both the heating element of the boiler and its core.

Second step. Place the resulting circle in a plastic pipe of a suitable size.

Third step. Make a winding on a plastic case from materials already familiar to you. Thanks to such a winding, the efficiency and productivity of the unit will be significantly increased.

Fourth step. Place the plastic housing in a quality insulating case. It will prevent possible electrical leaks and help to significantly reduce heat loss.

Heating will be carried out due to the contact of the coolant with the same winding. Winding and all further actions are carried out according to the same scheme as in the case of an ordinary induction installation discussed in the previous instructions.

Important notes on installation and use of the boiler

Homemade induction boilers are extremely easy to assemble, install and operate. However, before you start using this kind of heater, you need to know a few important rules, namely:

It is strongly recommended to equip the boiler pipe with a blast valve. Through this simple device, you can, if necessary, rid the system of excess air, normalizing pressure and ensuring optimal operating conditions.

Thus, using inexpensive materials and simple tools, you can assemble a complete installation for efficient space heating and water heating. Follow the instructions, remember the special recommendations, and very soon you will be able to enjoy warmth in your own home.

Good luck!

Video - DIY induction boiler

Does the induction heating circuit provide any real advantages? How economical is it compared to heating elements? How does an induction boiler work? Is it difficult to assemble it yourself? Let's try to answer these questions.

The photo shows a homemade induction boiler.

What it is

The essence of the phenomenon of electromagnetic induction, discovered by Michael Faraday in 1831, is that an electric current is excited in a conductor placed in a magnetic field. The effect, in particular, formed the basis of the operating principle of any modern transformer.

If you wind two insulated windings around a ferromagnetic core and apply, say, 220 volts to one of them, then a voltage will arise on the second, related to these 220 volts in the same way as the number of turns of the secondary winding is related to the number of turns of the primary.

Voltage with the required characteristics can be removed from the transformer windings and used to operate an electric motor or electronics. What if a ferromagnet that is not connected to anything is placed in the winding that generates eddy currents?

Obviously, the resulting EMF (electromotive force) is completely converted into the kinetic energy of movement of its molecules. Simply put - in heating.

Note: This is how induction cookers and melting furnaces work in steel mills.

Thus, at the output we will get a ready-made .

You just need to solve a few technical problems:

• Select a core made of non-corrosive material.
• Isolate it from the coil, while ensuring the tightness of the structure.
• Make sure that the coil itself does not overheat when large currents pass through it.

Advantages of an induction circuit

As a rule, the price of factory-made induction boilers is on average noticeably higher than that of heating element analogues, and starts from 20-25 thousand rubles with a 4-kilowatt device power.

Manufacturers and sellers give two arguments to justify the higher cost:

1. An induction boiler is more durable compared to its heating element counterpart.
2. It provides significant (up to 40-50%) energy savings, which will allow the costs to quickly pay off.

Let's try to evaluate the veracity of both statements.

Durability

Claims that the induction design is extremely resilient and durable are absolutely true.

Causes?

• There are no moving parts in the boiler. If so, there is absolutely no mechanical wear of the structure.
• It is free from the main problem of heating elements - liming of heating elements. Limescale gradually insulates the tubular heaters and causes them to overheat.

It’s curious: when eddy currents are excited in the core of the inductor, it vibrates barely noticeably, which promotes self-cleaning of the surface.

Economical

Let's remember the basics of physics.

• From the point of view of Sir Isaac Newton, energy does not go anywhere and does not come from anywhere. A perpetual motion machine is impossible; To heat a fixed volume of air by 10 degrees, you need to spend a strictly defined amount of thermal energy, regardless of the design of the heater.

• With any transformation of energy of any type, it ultimately either does physical work (that is, moves an object with non-zero mass against the gravity vector), or is used to heat the environment.

We emphasize: the efficiency of any direct heating electrical appliance is 100%.

All wasted electricity is completely converted into heat; For 1 kW of electrical power you can get 1 kW of thermal power.

Thus, the only thing that could theoretically explain the supposedly higher efficiency of an induction boiler is less heat dissipation in the environment.

This argument does not stand up to criticism:

1. When installing a boiler in a heated room, the heat not absorbed by the coolant is still spent on heating.

1. 50% lower heat loss with comparable or worse thermal insulation of the boiler body looks, to put it mildly, doubtful.

The conclusions are obvious:

• The market value of induction devices is unduly inflated.
• Their economy is, as one of Bulgakov’s heroes said, a typical case of so-called lies. The electrical power of the device is selected at the rate of standard 40 watts per cubic meter of heated room. Trying to heat a 200-meter house with a 4-kilowatt appliance will only lead to the recent buyer realizing that he was too naive.

crazy hands

Despite the piles of misinformation, the induction scheme itself more than has the right to life. The inflated market value quite naturally leads to the idea of ​​making induction heating boilers with your own hands. How to do it?

Frame

It should be:

• Dielectric.
• Durable enough.
• Allowing it to be hermetically connected to the heating circuit.

The simplest and most obvious solution is a polypropylene pipe with a diameter of 40 millimeters. Ideally, with fiber reinforcement, which will have a very positive effect on the strength qualities of the body.

Winding

In order to isolate the inductor, which heats up when power is applied, from thermoplastic polypropylene, it is advisable to glue several textolite strips over the housing. What to glue with? The simplest and most obvious solution is silicone sealant: it has acceptable adhesion to plastics and tolerates moderate heat well.

An important point: it is better to take sealants from reputable manufacturers (Ceresit, Moment, etc.).
Cheap sealants differ from them primarily in their much worse adhesion to problem surfaces, which, of course, includes smooth ones.

The coil itself is wound with enameled copper wire with a diameter of about 1.5 millimeters (section 2.25 mm2). The total length of the winding should be 10-15 meters. It is better to apply the coils with a small constant gap.

Core

What should it be like?

• Conductive. Eddy currents will not be induced in the dielectric.
• Ferromagnetic. A diamagnetic material will not interact with the electromagnetic field.
• Stainless. Corrosion in a closed heating circuit is clearly of no use to us.

Here are some possible solutions.

• A screw auger that fits tightly into the pipe. Moving along the grooves in it, the water will take away maximum heat.
• Chopped stainless steel wire. It is not very convenient because the improvised boiler will have to be enclosed on both sides by a metal mesh.
• “Hedgehogs” rolled from nichrome wire and tightly inserted into the pipe.
• Finally, the simplest instructions: in the same way, you can place metal (stainless) dish scourers in the pipe.

After the core has taken its place, the boiler is equipped on both sides with adapters from polypropylene with a diameter of 40 mm to DN20 or DU25 threads. They will prevent the core from falling out and will allow the boiler to be mounted in any circuit, leaving the connections collapsible.

Power converter

What will happen if we simply connect the inductor we wound to a power outlet?

Let's do a simple calculation.

• The resistivity of a copper conductor at +20C is 0.175 Ohm*mm2/m.
• With a cross section of 2.25 mm and a length of 10 meters, the total resistance of the coil will be equal to 0.175/2.25*10=0.7 Ohm.
• Consequently, when 220 volts are applied to the conductor, a current of 220/0.7 = 314 A will flow through it.

For comparison: when calculating wiring for copper, the cross-section is selected at the rate of 10 A/mm2.

The result is a little predictable: when a current is supplied more than 10 times higher than the calculated one, our conductor will simply melt.

The obvious solution is to reduce the supply voltage. The converter must be powerful enough to deliver at least 2.5 - 3 kilowatts.

A ready-made converter of such power can be a welding inverter with current regulation. The adjustment will not only protect the winding from overheating, but will also allow you to smoothly regulate the effective power of the heating boiler. With an inverter output voltage of 80 volts, the maximum power safe for the winding temperature will be about 2 kW.

Expenses

Of any significant costs, it is worth mentioning only a welding inverter (from 6,000 rubles) and a soldering iron for polypropylene (from 1,000 rubles). Another maximum of 1000 will cover all other purchases.

Conclusion

In the process of planning the installation of a heating system in a country house or in a country house, many try to solve the problem of excessive energy costs by installing an induction heating boiler. In addition to saving energy, its design is such that it avoids harmful emissions into the environment and does not pose any danger during use. An important argument in its favor is the possibility of its independent design. In this article we will look at what an induction heating boiler is: everything about the principle of operation + 2 do-it-yourself device options. In addition, its advantages over conventional electric boilers and gas units will become obvious to us.

Construction of induction boilers

The internal structure of such a boiler includes an inductor (transformer). Conventional household induction boilers are slightly different from similar industrial ones with a cylindrical winding system. Compact boilers for domestic use use toroidal copper windings.

The outer casing of the unit is made of painted metal, then there is a thick layer of thermal and electrical insulation, inside of which there is a double-walled core. It is made of special ferromagnetic steel and has a wall thickness of at least 10 mm. The toroidal winding that is wound on the core is the primary winding. It is in it that the energy of the electric field is converted into a magnetic one, which creates eddy currents. Their energy is already transferred to the secondary winding. The role of the secondary winding is the body of the circuit, which, under the influence of this energy, releases a large amount of heat that is transferred to the coolant. Toroidal winding allows you to create units with low weight and dimensions.

Operating principle of induction boilers

The standard package usually includes the boiler itself, an absolutely necessary semiconductor converter called an inverter, automatic switches, and an electronic thermostat. The temperature sensor itself is located inside the boiler body.

The operation of induction boilers is based on the principle of electromagnetic induction. Its essence is that electricity consumed from the network creates an electromagnetic field. The coolant is supplied inside the boiler through the water pipe, which is welded at the bottom. Alternating current with a frequency of 20 kHz is supplied to the boiler through an inverter. When this device is turned on, current flows through the toroidal winding of the boiler. In this case, the steel core heats up to a temperature of 750 degrees in just 7 minutes.

The heat produced is transferred to the coolant circulating inside the circuit. Rapid heating of the liquid creates convection currents. This means that the heated coolant expands greatly and rushes up the boiler structure and further into the heating system itself. Often this is enough for a domestic boiler with an average length heating circuit to operate fully. This method allows you to quickly heat the entire system, but for better circulation you need to additionally install a conventional circulation pump.

Thanks to the application of the principle of magnetic induction, heating of the coolant in such boilers occurs much faster than in units with heating elements, and heat losses are minimal. There is almost no scale on the core, no matter how hard and calcareous the water is.

This happens because the eddy currents cause the core to vibrate, preventing scale from forming. At the same time, bubbles boiling near its body clean the surface of the core. Due to the tightness of the entire system, the coolant absorbs the maximum (98%) amount of released thermal energy. Thus, these parameters greatly increase the efficiency of the boiler, which has a positive effect on its efficiency and service life.

Pros and cons of induction boilers

Induction boilers have a number of undoubted advantages over conventional boilers using heating elements:

• Stable efficiency indicators up to 99% for almost the entire service life.
• There are no heating elements, which significantly extends the life of the device.
• There are no moving elements, which completely eliminates mechanical wear and the need to replace components.
• The absence of detachable internal connections does not allow for leakage.
• Full availability of work even with direct current or low voltage in the network.
• Very fast heating to the desired coolant temperature (5 – 7 minutes).
• A fairly high degree of electrical and fire safety, corresponding to class II due to the use of a core not directly connected to the inductor.
• There is no need to install a chimney or provide a separate room for the boiler. To install this system there is no need to attract highly qualified specialists.
• The standard service life of the device is up to 25 years or even more. It directly depends on the tightness of the sealed external seam and on the large thickness of the metal pipes for the core. It does not require any maintenance work during its entire service life.
• The boiler can use all available coolant fluids: oil, water, antifreeze, ethylene glycol without any preliminary preparation.
• The coolant can only be changed once every 10 years.
• Good protection against overheating and various accidents, quiet operation.
• The boilers are equipped with electronic automated control systems.
• There is no scale inside the circuit.
• Possibility of connecting the boiler to any closed heating systems.
• The minimum possible heating of the coolant is 35°C.

But induction boilers have disadvantages, both compared to other heating devices and in terms of individual specific parameters.

• Such boilers can only be connected to a closed heating circuit, very often with forced circulation of coolant
• Quite a large weight of the boiler with rather small dimensions. The weight of a 2.5 kW boiler is at least 23 kg with a total height of 45 cm and a diameter of 12 cm.
• The price is higher than other boilers, which is due to the presence of an expensive part - an inverter.
• Radio interference generated at a distance of several meters from the boiler in the long-wave, medium-wave and even VHF range. They have no effect on the human body, but they are well felt by pets and electronic equipment.

Installation of an induction boiler and its control system

Installation of such boilers is only possible in a closed heating system. This requires an expansion tank and a pump for forced circulation of the coolant.

According to the instructions, the induction boiler is positioned strictly vertically. After this, the return pipe of the heating circuit is connected to the lower inlet pipe. The outlet is located at the top of the device (side or top). The supply pipeline is looped onto it.

The weight of the mounted boiler is quite serious, so special attention must be paid to the fastenings. They must be very reliable, taking into account the fact that when the boiler is operating, its weight will increase significantly due to the coolant entering inside. The lateral distance from the boiler to surrounding objects and walls is 300 mm. The distance to the floor and ceiling is 800 mm and no less. An important and mandatory condition for installing such boilers is their grounding. It is possible to use both metal and metal-plastic pipes with it.

A group of safety devices is built next to the outlet pipe: a blast valve, a pressure gauge, an air vent. The expansion tank is installed at a convenient location in the return pipe of the system. Shut-off valves are mainly installed after the safety group.

Installation of the entire control system, as well as the boiler itself, must be carried out in accordance with the existing rules and regulations of the Electrical Installation Code, diagrams and conditions contained in the technical data sheet included in the kit.

Examples of homemade designs

If you are not going to use an induction boiler for main heating in a private house, but want to equip a cottage or garage with it, then you can try to design it yourself. There are two options on how to do this.

First option

To implement it you will need pieces of plastic pipes and a welding inverter. Having basic knowledge of physics and knowing how to use wire cutters, you can independently make a basic induction model. To do this, you need to purchase an already created high-frequency welding inverter with continuously adjustable current power up to 15 amperes or even higher. To heat a large area, it is better to choose a much more powerful device. You will also need stainless steel wire rod or regular pieces of steel wire. This is necessary to act as a heated element. Their length is about 50 mm, with a diameter of 7 mm.

An important component is copper wire, which can be easily purchased at any specialty store. Do not use windings from old coils. The housing, which is the basis of the induction coil, is also part of the pipeline, so it can be made from a plastic pipe with thick walls. Its internal diameter should be 50 mm. Two outlet pipes are attached to this housing for the flow of cold coolant and the release of hot coolant. The entire internal space of the case must be completely filled with pieces of wire and covered with a metal mesh so that they do not spill out.

An induction coil is made as follows: an enamel-coated copper wire is gradually wound around a previously prepared plastic pipe. It will take approximately 90 turns. The resulting homemade device needs to be connected to the pipeline network. A small section of pipe is cut out of the pipeline, and a homemade induction boiler is installed in its place. It is connected through an inverter and the water is simply turned on.

Second option

This option involves the use of a three-phase transformer with the possibility of fixation. In addition, you will also need a welding machine. To make the device, you need to weld two pipes so that they look like a donut in cross-section. This design performs both conductive and heating functions. Then the winding is wound directly onto the boiler body in order to make it work more efficiently, despite its low weight and size. A standard coolant heating scheme is used here: it receives a large amount of thermal energy upon contact with the winding.

The manufacturing scheme for this design is somewhat more complicated than in the first version. The boiler is equipped with two pipes, both for the entrance of the cold coolant and for the exit of the heated one. If you come up with and build a protective casing yourself, you can minimize heat losses.

Features of self-installation and operation of homemade boilers

As in the case of factory-made boilers, only a closed-type heating system can be suitable for installing a homemade induction installation. It should include a centrifugal pump, which creates constant circulation of the coolant inside the heating system. The plastic pipelines that are common today are ideally suited for installing a homemade induction boiler. All regulations related to the installation of store boilers must be fully observed in this case. If you install controls and safety devices on the system, then your homemade installation will be little inferior to its factory counterparts.

Although it is quite difficult to make such a device, and it is better not to take on this task without “direct hands”, it is a pleasure to operate it. After all, along with ease of use, we also get serious energy savings.

Owners of private houses have many options for heating system equipment. But most often the choice falls on induction boilers. And this is not surprising, because such an installation has a number of advantages. Externally, an induction electric boiler is somewhat reminiscent of a transformer installation. There are no heating elements. Water is heated by electromagnetic induction.

What electric induction heating boilers are, what advantages they have and how to make them yourself will be discussed in this article.

The high popularity of induction boilers is due to their advantages. Among the main ones we can name profitability. The installation allows you to save electrical energy. By equipping a heating system with an electric boiler, you can forget about the need to regularly replenish fuel supplies. What cannot be said about systems with liquid fuels and...

Induction electric boilers operate silently. The device does not emit harmful substances during operation and is environmentally friendly. Another advantage is that the electric coil is isolated and does not come into contact with the coolant. This means that there is no possibility of a leak.

The induction device is durable and safe.

In addition, such equipment can be quite easily made on your own.

What is needed to make a boiler?

Thus, induction-type boilers have plenty of advantages. But there is one drawback - high cost. But this flaw can be easily corrected. After all, making an induction boiler with your own hands is not difficult.

The cost of installing induction equipment quickly pays off due to its high efficiency and electrical safety.

By making your own drawings for an induction boiler, you can easily and quickly create an economical and efficient heating system for your home.

In order to build an induction type boiler, you will need the following tools and materials:

Thus, no special and expensive tools and materials are required to create an induction device. Every owner probably has all the necessary equipment and materials. By making your own drawings for an induction heating boiler, you can end up with a heat generator that is quite economical to operate and cheap to create and install.

Algorithm for creating an induction boiler

Having prepared all the tools and materials, you can start working. At first it may seem that making an induction boiler yourself is not easy. But in reality it is not difficult at all. The main thing is to adhere to the algorithm and follow the rules.

In order to make a boiler based on an induction stove, it is necessary to perform the following work:

To make the operation of the equipment safer, it is better to insulate the open areas of the copper coil. When choosing an insulator, thermal and electrical conductivity should be taken into account. You can read about other homemade heating products.

Homemade induction boiler - reality

Thus, making induction heating boilers with your own hands is very simple. In addition, the price of a homemade boiler is cheap. The only drawback of such a unit is its unsightly appearance and small size. But having installed such a boiler, you can immediately feel the positive effect of its operation; the heating rate of the coolant in the heating network increases significantly.

When choosing a boiler for heating a home, owners are guided, first of all, by what heating source is available for the room. Gas is the cheapest fuel, but not all populated areas are supplied. Electricity is the most common, but not the cheapest. An induction heating boiler produces a fairly high efficiency, with lower electricity consumption compared to other electric options.

The basis of the principle of operation of the boiler is the creation of thermal energy from electrical energy. The action of electromagnetic induction is as follows: we pass current through a coil wound with wire, and an electromagnetic field appears around this winding. A metal core placed in a coil (which tends to be attracted by a magnet) will begin to heat up quickly.

Heat Generator Mechanism: It is an electrical inductor consisting of a primary winding, a secondary winding and a core. By converting electricity into eddy currents, the primary winding directs the electric field to the secondary winding, which in turn transfers energy to the carrier. Under the influence of the electromagnetic field, eddy currents are formed in the body and core. They heat up the metal. The water takes heat from the core and distributes it throughout the building.

The operation of an induction cooker is based on the same principle. Such tiles are much more economical compared to conventional electric stoves. This is achieved by the absence of heat loss when transferring heat from the heater to the cookware. Marketers today refer to induction heating boilers as advanced developments created on a new principle. But in reality, this is not entirely true. Inductive principles have been used since the last century for smelting furnaces. Also, no new materials are used to make the boilers.

M. Faraday discovered the phenomenon of induction in 1831.

Induction options are safer compared to other heating boilers and require virtually no maintenance. They do not contain dynamic parts and, as a result, have no mechanical wear. With sufficient cooling, the service life of the coil is unlimited. Such boilers do not require a separate room. Compared to, they practically do not require preventive work.

Advantages of an induction boiler:

• Constant coolant circulation;
• Lack of heating elements;
• Silence.

An inductive electric boiler can heat not only the area of ​​a small private house, but also industrial premises, without requiring large installation and maintenance costs. Induction heating boilers on the market are not cheap. The reason is in the system sensors. The inverter used in the control system increases the cost of the heating boiler.

How to make an induction heating boiler with your own hands

Opponents of installing induction boilers cite the law of conservation - 1 kW of electricity is capable of generating no more than 1 kW of thermal energy. Yes, any water heater, consuming 1 kW of electricity, also produces 1 kW of energy. But not all of it is thermal. Induction water heaters are more productive in the production of thermal energy, in comparison with heating elements. Making a homemade inductive water heater is not difficult. The materials used can be found without much difficulty and at low prices. The circuit of such an inductive device is quite simple.

To convert electricity into heat, you need:

• Inductor;
• AC 50 Hz;
• The core is made of a material to which the magnet “sticks”;
• Drawings of an induction heating boiler (not a problem to find).

For the body of the induction boiler you need to take a pipe with a diameter of 5 cm. The pipe is filled with pieces of wire, 5-7 cm, with a diameter of no more than 7 mm. To connect the boiler to the pipe system, you will need adapters. A diagram of the heating system will help determine the characteristics.

It is better to install an automatic power outage in the event of a coolant leak. In this case, the electromagnetic field will not disappear unless the power supply is turned off, and the housing and fasteners will simply melt.

We make an induction coil - the main heating element. To do this, take copper wire and wrap it around the body, approximately 85-99 turns. We keep the interval between turns equal. The simplest induction boiler is ready. Such an inductor can be installed anywhere in the pipeline. An induction steam generator operates on the same principle.

Find out about the advantages and disadvantages of a double-circuit boiler in the following material:

Modernization of induction heating

Induction heating systems often have favorable reviews. Silence, efficiency and longevity are the indisputable advantages of the heating system. One type of system is the operation of an induction water heater for heating. An induction water heater can be purchased and installed in the pipeline system.

You can choose an induction heating circuit with your own hands. In this case, you can save your money well.

But, for more efficient operation of the induction system, it is important to know some nuances. When installing an induction cooker into a structure, it is connected to a charger, batteries and an inverter. An inverter is a device that converts direct current into alternating current. Its use reduces the amount of electricity consumed for the heating system to virtually zero.

For less energy consumption, you need:

• 4 kW inverter;
• 2 batteries 250 Ah;
• Device for charging batteries.

We connect 2 batteries synchronously and charge them. Direct current is generated in them and supplied to the inverter. The inverter converts direct current into alternating current. The inverter then transfers current to the induction cooker and the charger continuously charges the batteries. Thus, the consumption of the 24 V charging device is the energy consumption of induction heating at home. We calculate the costs for the pump separately. Induction heaters are used only in versions with forced circulation.

Description of the inverter heating boiler

The inverter boiler became available to household consumers, unlike industrial enterprises, relatively recently. The boiler structure is based on 2 main cylinders placed in the outer one. This boiler option is safer. With proper installation, fire safety is orders of magnitude higher compared to gas, coal and wood boilers.

Operating principle of the inverter boiler:

• The coolant flows in the inner cylinder;
• A cylinder that passes current through itself ensures heating of the coolant;
• The outer cylinder acts as a heat insulator;
• The basis of the boiler operation is electromagnetic induction.

The inverter boiler mechanism virtually eliminates coolant leaks. An important quality is that any option can be used as a coolant (water, antifreeze, oil). The advantage of using antifreeze is that when the boiler is turned off in winter, the battery will not freeze or burst. Small power inverter boiler models often have the ability to operate on battery power, which significantly reduces energy costs.

When installing an inverter boiler into a heating system, it is important to properly connect the grounding.

The inverter system will allow you to quickly reach the desired temperature and ensure economical consumption of electricity. Such systems are successfully used in the production of split systems. An inverter air conditioner has a much longer service life than standard split systems.

DIY induction heating boiler (video)

Induction devices are practical and economical systems that do not require difficult installation and maintenance. As a rule, their small dimensions allow installation in any room and do not require restructuring of the heating system. The fire safety of induction heating boilers allows them to be used in country houses, even if the owners do not appear there often.
